How to add embedded images to notification email templates?
In this page we discuss how to add embedded images (that are part of the email message instead of being referenced from an external source, e.g. the internet) as data URIs to Managed File Transfer email templates.
A data URI for an image is a way to embed the image data directly into a web page or document by encoding it as a text string, allowing it to be displayed without the need for a separate file.
To obtain a data URI for an image, you can use online converters or code it manually by encoding the image data in Base64 and prefixing it with "data:image/png;base64," (or the appropriate MIME type) followed by the encoded data.
For further details see https://en.wikipedia.org/wiki/Data_URI_scheme.
Go to your Managed File Transfer email template page and select Tools / Source code.
Find or create the <img> tag which you want to embedded. Paste the "data URI" of your image in the src attribute of the <img> tag.
Save the dialog and the email template.
